Circle the best answer, or write your answer on the line.

  1. In Cu + 2 AgNO₃ → Cu(NO₃)₂ + 2 Ag, 6 silver atoms form on a wire. How many copper atoms reacted, Ari?

  2. In Cu + 2 AgNO₃ → Cu(NO₃)₂ + 2 Ag, 8 silver atoms form on a wire. How many copper atoms reacted, Esme?

  3. In Zn + Cu²⁺ → Zn²⁺ + Cu, which particle loses electrons, Jun?

    • The zinc atom
    • The sulfate ion
    • The copper ion

  4. Copper in silver nitrate solution turns the liquid blue. Why, Luz?

    • Blue Cu²⁺ ions enter the solution
    • Silver ions in it turn blue
    • Nitrate breaks down into a blue dye

  5. Milo says copper will replace zinc in zinc sulfate solution. Agree or disagree?

    • Disagree: copper is below zinc
    • Agree: copper is above zinc
    • Agree: copper is the heavier metal

  6. Noah says silver will give hydrogen bubbles in dilute hydrochloric acid. Agree or disagree?

    • Disagree: silver is below hydrogen
    • Agree: acids dissolve any metal they touch
    • Agree: silver is above hydrogen

  7. Pia says if zinc replaces copper, copper must also replace zinc. Agree or disagree?

    • Agree: the two metals are equally active
    • Agree: the swap works both ways
    • Disagree: it runs one way

  8. Read this first

  9. Using the results, which metal is the most active, Ren?

    • X
    • Z
    • Y

  10. Using the results, which order runs from most to least active, Tala?

    • Z, X, Y
    • X, Z, Y
    • Y, X, Z

  11. Using the results, why does Y show no change in either solution, Zee?

    • Y is the least active of the three
    • Y is the most active of the three
    • Y did not touch either of the solutions

About this worksheet

Single replacement reactions and the activity series. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can use the activity ladder: a metal replaces any metal below it, and metals above hydrogen replace hydrogen from acids.
  • I can predict products, or no reaction, for a metal in a salt solution or dilute acid.
  • I can use the halogen order F₂, Cl₂, Br₂, I₂ the same way.
  • I can rank metals from results and say which particle loses electrons.

Standard: HS-PS1-2

Words to know

activity series: A list of metals, most active first

single replacement: A + BC → AC + B: a lone element swaps into a compound

more active: Higher on the ladder; replaces the metals below it

no reaction: The lone element is lower, so nothing swaps

spectator ion: An ion that stays the same on both sides, such as sulfate

Common mistakes

Your child matched one silver atom to each copper atom. The equation's 2 in front of Ag means two silver atoms per copper atom.

Your child used the 3 in front of Zn but not the 2 in front of Al. Two aluminum atoms make three zinc atoms.

Your child multiplied by 2. Each copper atom makes two silver atoms, so the copper count is the silver count divided by 2.

Questions parents ask

What is the most common mistake with single replacement reactions and the activity series?

Your child matched one silver atom to each copper atom. The equation's 2 in front of Ag means two silver atoms per copper atom.
